Try to inflict the plague status effect. Plague causes it to lose 10% of its life per turn, and reduces it's RS by 50%, which increased the damage it takes from physical attacks quite a bit. Although you may prefer to just inflict plague and then focus on surviving while its HP is slowly eaten away by plague. I'd recommend using both Sarah and Wendala for the battle, and have them both focus on getting their defense+ auras into effect while also keeping everyone healed.
For reference, plague only comes from using regular attacks with one of a select few weapons equipped. At that point in the game, I believe either an Omen Blade (Random) or Cerberus Jaws (Brussian) would be your only options. If you have a stronger weapon that inflicts plague, then by all means feel free to use it.
This should at least get you to the second part of the battle, unless you're simply unable to survive seven rounds of battle even in full defense mode with auras and heal spells being flung around. If that's the case, then you may just need to bite the bullet and level up your characters a bit higher.
